Knob & Tube Removal

Is your home or workplace still using knob and tube wiring?  If so, you need to replace it now!

Knob and tube wiring is an outdated wiring method used since the late 1800s and was very popular until 1945. The system involved stringing of individual conductor insulated wires across porcelain insulators called “knobs” and “tubes.” This wiring technique has now outlived its usefulness and is considered unsafe.Take a look at the following drawbacks of the old “knob and tube” wiring system to find out why:

  1. With the old system there is a greater chance of shock, electrocution, and damage to sensitive devices because it is an ungrounded system.
  2. Because of age and deterioration, fire risk is increased substantially.
  3. Often, new wiring is not connected to old knob and tube wiring properly, increasing the chances of shock and fire, reverse polarity, overloaded circuits, and switched neutrals.

So what are you waiting for? Get that unsafe wiring out of your home or workplace.
